| 中文摘要: |
| 域名系统(DNS)服务在Internet服务中占据着非常重要的地位，但在最初设计DNS时却没有考虑它的安全问题，导致系统存在很多安全漏洞，针对它的安全脆弱性。对当前DNS遭受的网络攻击进行了深入分析，提出并剖析了一系列当前采用的安全防范措施；文中重点探讨了DNS安全扩展(DNSSEC)的安全防范思想、工作原理，然后对DNSSEC做了性能评价，提出相关建议．最后在总结全文的基础上对DNS安全研究提出展望。 |
| 英文摘要: |
| The domain name system (DNS)plays an important role in internet services .But it is found vulnerable in many aspects because the original DNS specifications didn't take security into consideration. In this paper, we analyze the current network attacks against DNS, propose a series of defending policies, and make some comments on them. Then we study the primary defending rules and working theories of DNSSEC,and analyze its work flow and evaluate its performance. Finally we summarize this paper and show the developing trend of DNS security. |
